I am interested in pygmys....although, they need to have an area around them for me to place a tripod. Walls don't work for me other than wide angle. Shooting macro video with a dslr has it's limits...

Seraya had a sea fan at about 25m on a sloping sand bottom for you to set up a tripod. couple of good sized bargibantis with 2 which were pregnant when i was there earlier this month.

Jonny, it's true that sometimes you need more than one encounter of the same creature to put together the footage, but I doubt he is that lucky to find two flamboyance cuttlefish eating the same type of shrimp.

It's good to know the the Olympus 12-50 lens is possible to get close to that kind of result. I think I'm going to invest in one of this since it's cheap and might come in handy:

I just bring myself to spend US$250 for a subsee adapter to just flip the lens in and out.......

I have 4 of these magnets. They work as advertised. I have loaded a subsee and 1-2 more Fun-in +5 diopters stacked with no issue. Any more and it might drop off on land. There's always a danger of a force coming from the side dislodging the lens but if it is just one lens then the risk is quite minimal.

One caveat. the magnets also gets a bit of sand stuck on it underwater. The type of black sand with iron content. So you'll need to clean it off from time to time.

I been using the Maha 8 Cell charger for a number of years. Just changed a new charger last year as the old one had some internal corrosion. Watch out those bringing out on LOBs or areas which get salt spray!!

Batteries i started with the maha 2700mah ones but now i'm using a Sanyo Harmolattice which looks similar to the XX series. 2500mah eneloop style. I also have the Maha imedion 2400mah. Both work well without any issue and hold the charge well.
